Dipstick Dip Stick popped, popping, blow, blowing, blew out [Merged]

[scrcco]

I just installed a different head after my timing belt went. Everything is back together and the break-in period is over. Last night i revved past 5,000 rpm. for the first time and noticed it was struggling, I let off at 5,500. Then a riced-out Honda cruised by so i stepped on it, went to about 6,000 rpm's, now theres a huge cloud of smoke behind my car. I opened the hood to notice my dipstick shot up, and oil sprayed all over the underneath of my hood, then dripped all over the motor and exhaust. What could be the problem? I already replaced the PCV valve and does the same thing???

"Hole in piston or chip in the side" and that is your answer...

Dont take anyone's advice except for oldman's and ddavisaf. Everything they've said is factual and is most likely the problem, along with testing all of this, after you get this settled, id recccomend investing in a tune up, and an oilchange--no synthetic,and id also invest in some Lucas oil stabalizer, it will help in longevity of the engine, reduces ticking, and leaks. And if your having problems locating the PCV valve, if your facing towards the front of the car, looking at the windshield standing right in front of it, lean over the engine, look directly behind the valve cover, and there will be a little metal nipple looking object, it screws in, just remove it and replace it with the new one. and for the breather, thats the hose(or small filter if its replaced) on the left side of the valvecover if your facing it directly once again. And when he refers to TDC that means Top Dead Center, which is saying that the cam dowels are at 12 oclock. your compression for the cylinder's should be about 150 across the board. Your gaskets are probably old, and tattered, and hardly even existing for that matter by now. You would be wise to look into that. Have a buddy help you so you dont have to tackle all this by yourself, its hard to locate a leak like that. best of luck to you

I'll go for -10 AN size, but dose anyone know how to convert AN to inch or mm

Also what you think of using 12v SMALL vacuum pump between valve cover and catch can ... the pump maximum vacuum will be not more than 20 Hg and activated by the boost at 1 bar.

This is probably a dead thread, but to answer your question... to convert AN to standard, just put the -an size over a 16th, then convert it over. i.e.: -6 AN= 3/8 in. -10 AN= 5/8 in. etc.

I pinched my dipstick tube as well with no side effects and I also was looking for a way to keep the intake clean with use of catch cans or breathers. I decided the best would be to leave it all hooked up to stock locations but I did not want to spend a lot of money doing it. I bought a small inexpensive fram fuel filter and mounted it in the breather line. It will allow you to hook up to the intake and it will catch and separate the oil. Since the filter is made of a somewhat translucent plastic you can see how much oil is in the filter. When it starts to get full you can just pop a new one in there. I have had one on my car for a good year and a half; (the car has been running off and on for a total of about 6 months in that year and a half due to unrelated issues), never had to change it and no side effects what so ever with about a teaspoon or two of oil in the filter.


By the way if anyone has any reason for this to be bad then please let me know, but I have never had any problems.

I recently bought a 1G Eclipse GSX 5-speed, and when i got it it had an exhaust leak (crack in the manifold) when i got it home (30-40 mins) i noticed that the dipstick was up a couple inches, and i know that it was down before. Some oil had came out of it, but not much. The owner said the boost was set at 17 psi, but since there was an exhaust leak, i didnt boost it much. (i got it to 13 and let off) so please let me know what i should do to keep the dipstick from popping.

The search button does amazing things here but you can start with checking that the PCV valve isn't leaking boost into the crankcase and causing the dipstaick to pop out. When you apply pressure to the PCV valve from the side with the hose barb nothing should come out the threaded side.

You can get a new oring for the dipstick, or get a new dipstick. I think summit had billet aluminum dipsticks a while back for like $15-20.
Getting the dipstick to seal better may just be covering up a problem.

 

[evil talon]

I had the same problem. I believe mine wouldn't stay down so I just twisted the dipstick while it was all the way down(pretty much bending the stick slightly) causing it to stay down while still giving a correct reading.

Listen to this man. Your dipstick popping out is a symptom of a problem. Locking the dipstick down is not going to fix anything. You need to get to the root of things and fix the problem. In this case you are building crankcase pressure. It could be the PCV like Steve said but there is also blowby and the valve cover breather to factor into the equatioin. PCV valves from the dealership are cheap (although once in a while you'll find a bad one) if that turns out to be your only problem. Make sure your breather is also functional, it's another point to relieve pressure. Also, do a compression test to cover all bases.

A buddy of mine has a 97 gst....evoIII 16g 580 injectors.for some reason when he gets on it the dipstick blows out and the oil cap he already replaced the dipstick and the o-rings why could this be?

 

[VelocitàPaola]

The crankcase is being pressurized somehow. Check/replace the PCV valve.

 

[yekrahs]

I had the same problem becuase I capped off the crankcase pressure release tube on the left side of your headgasket...maybe check that...sorry I'm tired and can't think of correct termanology

 

[my98gsx]

i have the same problem with my 1998 GSX... my pcv valve is new too. the ony thing i could do to fix the problem was to put a 1st gen dip stick on my car. Im building a 6bolt motor for my car and i had an extra dipstick lying arround... the one that came on my car was cheep plastic and blew out all the time, the 1st gen is metal on top and has a much nicer seal on top and i havnt had a problem since...

 

[kenamond]

In the stock configuration, there are two possible outlets from the crankcase: VC breather (passenger side of VC) and PCV (rear, passenger side of VC).

At idle, air is sucked through the PCV out of the VC/crankcase due to the vaccuum in the IM. Under boost, the PCV closes, and excess crankcase pressure vents to the intake pipe through the VC breather.

Check that the VC breather is not capped or there's no where for the crankcase to vent.

If the PCV is bad and letting air into the VC, the boosted/pressurized IM will pressurize the crankcase. I'm not sure if the VC breather can vent that inflow of boosted air quickly enough.

Make sure the VC breather is recirculating or dumping to a catch can, and check that the PCV is functioning properly (unscrew it, disconnect the hose, and try to blow through it from the end that was connected to the hose). If it is bad, don't replace it with an Autozone/Carquest/etc. unit, as these don't work. Get an OEM one from a mitsu dealership for $4.

If he has some form of catch can setup on his PCV, you'll need to provide more information, because you can set these up incorrectly leading to problems such as popping the dipstick tube out of the block. Do a search for PCV catch can setups for more information.

I have done some researching and haven't seen any advice other than changing the PCV valve. My dipstick pops out when I boost and am at high RPMS. What else can I check for problems? I would really appreciate some help on this, I am really tired of oil spraying in the engine bay. It might be my oil catch can, started soon after installing the catch can, so I have removed the catch can, but I want to know what else to check. Thanks in advance everyone, rep points for anyone that can help me out and solve the problem.

 

[WillyC]

Your catch can has some kind of vent so that it is not a sealed system...right? Your rings could be going out and the blow-by is causing it.

The catch can is sealed. I doubt it is the rings or at least I hope it isn't because the engine was rebuilt February 2005.

 

[WillyC]

The catch can has to be able to vent the pressure from the crankcase. How would it escape if it was in a sealed system??? You need to vent it somehow.

Okay let me rephrase what I meant. There is a line that goes from the valve cover to the catch can, then a line going out of the catch can into the air intak snorkel. So in that case it is sealed.

 

[ROOKIE1]

Get a new dipstick. The seal on stick is probably dried out and not fitting tightly enough .

I don't know how often they should be replaced, but mine was replaced 8 months ago. The O-rings are not dried out yet on it. Anything else I can check?

They said it should not be sealed at all .

 

[twack]

take a pliers and squeeze the top of the dipstick tube if you make it snug enough it will stay. i did it to mine and i havnt had any oil spray for 8 months

This is also the ghetto fix ...
